You think it might be personification?
It is the reason something exist for example if you ask what the purpose of a car is you would say its purpose is to get me from one place to another.
There should be a period after writing it should look like this : " writing. She can"
the sentence also says "through her words" when after "words" , there should also be a period.
Other than the missing periods your sentence seems fine.
You could also use a comma after "writing" instead of a period and make the S in "She" a lower case.
I hope this helps you.
